Including to the sense of urgency with this month’s patch batch from Redmond are fixes for 2 different weaknesses that now have public proof-of-concept exploits accessible.
Microsoft and several other safety companies have disclosed that attackers are exploiting a pair of bugs within the Home windows Frequent Log File System (CLFS) driver that enable attackers to raise their privileges on a susceptible machine. The Home windows CLFS is a essential Home windows element chargeable for logging providers, and is broadly utilized by Home windows system providers and third-party functions for logging.

Kev Breen, senior director of risk analysis at Immersive Labs, stated privilege escalation bugs assume an attacker already has preliminary entry to a compromised host, usually via a phishing assault or by utilizing stolen credentials. But when that entry already exists, Breen stated, attackers can achieve entry to the way more highly effective Home windows SYSTEM account, which may disable safety tooling and even achieve area administration degree permissions utilizing credential harvesting instruments.
“The patch notes don’t present technical particulars on how that is being exploited, and no Indicators of Compromise (IOCs) are shared, which means the one mitigation safety groups have is to use these patches instantly,” he stated. “The common time from public disclosure to exploitation at scale is lower than 5 days, with risk actors, ransomware teams, and associates fast to leverage these vulnerabilities.”
Two different zero-days patched by Microsoft right now additionally had been elevation of privilege flaws: CVE-2025-32709, which considerations afd.sys, the Home windows Ancillary Perform Driver that permits Home windows functions to connect with the Web; and CVE-2025-30400, a weak spot within the Desktop Window Supervisor (DWM) library for Home windows. As Adam Barnett at Rapid7 notes, tomorrow marks the one-year anniversary of CVE-2024-30051, a earlier zero-day elevation of privilege vulnerability on this identical DWM element.

Mentioned baggage contains new synthetic intelligence (AI) capabilities, together with the controversial Recall function, which consistently takes screenshots of what customers are doing on Home windows CoPilot-enabled computer systems.
Microsoft went again to the drafting board on Recall after a fountain of destructive suggestions from safety consultants, who warned it might current a sexy goal and a possible gold mine for attackers. Microsoft seems to have made some efforts to forestall Recall from scooping up delicate monetary data, however privateness and safety considerations nonetheless linger. Former Microsoftie Kevin Beaumont has teardown on Microsoft’s updates to Recall.
In any case, windowslatest.com experiences that Home windows 11 model 24H2 exhibits up prepared for downloads, even should you don’t need it.
